The stem upper end is vertically disposed with bearing inserted link, limited step, and the jack inner wall of the inner piston is provided with axis
Cylinder accommodating concave station.
Further, it is additionally provided with above the beam barrel accommodating concave station and keeps away a concave station.
Further, the fixing seat is provided with connecting hole, and the stem lower end, outer sleeve bottom surface are provided with screw thread
Hole, bolt passes through the connecting hole and the threaded hole assembles, and the stem, outer sleeve is made to be removably connected to the fixation
Seat.
Further, the inner piston bottom is provided with gear rotary table, and the outer sleeve upper opening inward flange is provided with gear
Circle of position ring；The diameter of the gear rotary table is greater than the diameter of bore of the gear annulus.
Compared with prior art, interior the utility model has the following beneficial effects: (1) stem can position bearing
Piston can position beam barrel, and then when pushing beam barrel, and positional shift will not occur for beam barrel, guarantee that bearing is accurately pressed into axis
In cylinder, concentricity and verticality are complied with standard, and not only ensure that quality of finished, also improve working efficiency；(2) stem, housing
Cylinder is detachably connected with fixing seat, can be replaced according to bearing specification, pedestal specification to stem and inner piston, and jig is improved
Versatility.

Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
As depicted in figs. 1 and 2, embodiment provided by the utility model, a kind of 3 press-in jig of bearing of fan base 1, packet
Fixing seat 10, stem 20, inner piston 30 and outer sleeve 40 are included.
20 lower end of stem is removably connected to fixing seat 10；Inner piston 30 is movably set in outside stem 20, inner piston 30 with
Spring is provided between fixing seat 10；Outer sleeve 40 is sheathed on outside inner piston 30, and 40 bottom of outer sleeve is removably connected to admittedly
Reservation 10.Wherein, inner piston 30 can move up and down in outer sleeve 40 along stem 20；Also, under the action of the spring, inner piston
30 remain the trend moved upwards.
Fixing seat 10 is provided with connecting hole 11, and 20 lower end of stem, 40 bottom surface of outer sleeve are provided with threaded hole, and bolt 12 is worn
It crosses connecting hole 11 and threaded hole assembles, stem 20, outer sleeve 40 is made to be removably connected to fixing seat 10.
30 bottom of inner piston is provided with gear rotary table 33, and 40 upper opening inward flange of outer sleeve is provided with gear annulus 41；Gear
The diameter of circle of position platform 33 is greater than the diameter of bore of gear annulus 41.Wherein, the cooperation of gear rotary table 33 and gear annulus 41, can
The height that limitation inner piston 30 moves upwards, and then inner piston 30 is avoided to be detached from outer sleeve 40.
20 upper end of stem is vertically disposed with bearing inserted link 21, limited step 22.The jack inner wall of inner piston 30 is provided with axis
Cylinder accommodating concave station 31, beam barrel, which accommodates to be additionally provided with above concave station 31, keeps away a concave station 32.
As shown in Figure 1, bearing 3 is sheathed on outside bearing inserted link 21,22 upper surface support bearing 3 of limited step；2 lower end of beam barrel
It is inserted in beam barrel accommodating concave station 31, bearing 3 is not pressed into 2 top of beam barrel；1 lower surface of pedestal is butted on 30 upper surface of inner piston.
As shown in Fig. 2, hold-down devices (being not drawn into figure) push pedestal 1, forces beam barrel 2 to move downward and be inserted into
Beam barrel is accommodated in concave station 31 and is put down, and bearing 3 is made to be pressed into 2 top of beam barrel.Wherein: it is downward that beam barrel accommodating concave station 31 can limit beam barrel 2
The direction of movement avoids beam barrel 2 that position occurs and deviates.
When bearing 3 is pressed into 2 top of beam barrel, 2 top of beam barrel can be deformed, and diameter can become larger；Keeping away a concave station 32 can be axis
Cylinder 2 provides the space of deformation.
Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly
Interest field, therefore equivalent variations made according to the claim of the utility model still fall within the scope of the utility model.
